I purchased a new 8Tb G-RAID Thunderbolt 3 drive unit a few weeks back to use with a Dell 2 in 1 Laptop, our thinking isthat as it comes with a HDMI port, when the unit is in the office you can plugin an external monitor and give the Laptop more workspace.

The problem is that we cannot get it to work at all, we know that the monitors work, and we have purchased various new cables just in case it was a lead issue, we have tried various costing between £19-£75 and cannot get anything on the monitor.

We then purchased a second drive (as they are useful) and get the same results with this.

In order for the HDMI port to work as a pass-through it requires the drive to be attached to the computer via TB3. So if you are plugging it in via the USB-C connection it cannot pass a video signal through the device.
